uesing a jpitch gauge is simple; just line up the strait edge of the gadge paralel with your flybar and then read the pitch

And there's loads of YT videos on the subject which explain it all in great detail (assuming you've got broadband.)

ok im confused i took my heli to ultimate hobbies to get the guys there to help me get these servos working the right way, to make a long story short i would have struggled with those servos because they were analog and my tail was digital and they were conflicting so i traded the servos back to the place i bought them from for top of the line digital servos all around .

the thing that is confusing me is when i was at ultimate they guys said when i push throttle up the whole swashplate should go down ????
is this right my 130 x goes up when i throttle up not down ????

The swashplate on the 450 3d goes down when you raise the throttle. Same on the b400. So the 450-x is most likely the same even though it is flybarless. Sorry can't be any help on the pitch gauge.

This depends on the control links to the blades. All blades are (normally) controlled by links to the trailing edges. However, some heads have rockers in the linkage that will reverse the movement. These like many T-rex will move the swash down to increase pitch. Others like both of my 450s and B400 move the swash up to increase pitch.

The answer lies in the linkage control set-up but this makes no difference to how the head is set up. You still require the head to be level at mid/high/low-stick with the correct collective pitch at low & high stick and the correct cyclic angles at mid-stick.

Tom.

I your right i think i got it i can hover it kindof im having trouble getting the trim inn the ar7200 close enough to keep it in place indoors no wind it keeps wanting to drift and since i cant use the trim on my radio i could not figure out how to change the resolotion of the stim settings in the beast x

but im going to give my self a pat on the back for finnally getting it right on my own...


i did take it a couple places but i ended up getting mixed info and it made things worse i found out the hard why the importants of level swashplate the leveler you get it the better it works so i took her to work and use the suface plate and hight gauge all around and adjusted my control rods to level i wonder if im off alittle and thats why its drifting i better check it out since ive only flown it once after i got it working Rolling Eyes

ok guys whats the trick i got the thing to kindo of fly but how do i get it to not drift around i heard these things were steady and stable but it seems im always having to correct it to hold in place.

ive tried using the trim in the ar7200 since it says not to trim it in the radio

but its like the resolution is to course to get it just right

and i also get a nasty tail wag some times when i stop a turn quickly

Hi NOMFTOTF,

You need a tool for setting the pitch on the flybarless head. Unscrew the brake disk from the rotor housing and fit the tool in its place: line up the top of the pitch gage with the cross bar of the setting up tool screwed onto the rotor housing.

http://www.wingswheelsandrotors.com/blh4302-blade-450-x-flybarless-setup-tool-5592-p.asp

On the 450X the pitch links are to the rear of the blade holder, so when the swashplate goes down the leading edge of the blades go up and the pitch is positive.
